# Shorewall version 1.2 - Rules File
|
|
#
|
|
# /etc/shorewall/rules
|
|
#
|
|
# Rules in this file govern connection establishment. Requests and
|
|
# responses are automatically allowed using connection tracking.
|
|
#
|
|
# In most places where an IP address or subnet is allowed, you
|
|
# can preceed the address/subnet with "!" (e.g., !192.168.1.0/24) to
|
|
# indicate that the rule matches all addresses except the address/subnet
|
|
# given. Notice that no white space is permitted between "!" and the
|
|
# address/subnet.
|
|
#
|
|
# If any of the following columns contain the word "none" then the rule
|
|
# is ignored:
|
|
#
|
|
# PORT(S), CLIENT PORT(S), CLIENT(S) and SERVER.
|
|
#
|
|
# Columns are:
|
|
#
|
|
#
|
|
# RESULT ACCEPT, DROP or REJECT
|
|
#
|
|
# ACCEPT -- allow the connection request
|
|
# DROP -- ignore the request
|
|
# REJECT -- disallow the request and return an
|
|
# icmp-unreachable packet.
|
|
#
|
|
# May optionally be followed by ":" and a syslog log
|
|
# level (e.g, REJECT:info). This causes the packet to be
|
|
# logged at the specified level.
|
|
#
|
|
# CLIENT(S) Hosts permitted to be clients. May be a zone defined
|
|
# in /etc/shorewall/zones or $FW to indicate the
|
|
# firewall itself.
|
|
#
|
|
# Clients may be further restricted to a list of subnets
|
|
# and/or hosts by appending ":" and a comma-separated
|
|
# list of subnets and/or hosts. Hosts may be specified
|
|
# by IP or MAC address; mac addresses must begin with
|
|
# "~" and must use "-" as a separator.
|
|
#
|
|
# dmz:192.168.2.2 Host 192.168.2.2 in the DMZ
|
|
#
|
|
# net:155.186.235.0/24 Subnet 155.186.235.0/24 on the
|
|
# Internet
|
|
#
|
|
# loc:192.168.1.1,192.168.1.2
|
|
# Hosts 192.168.1.1 and
|
|
# 192.168.1.2 in the local zone.
|
|
# loc:~00-A0-C9-15-39-78 Host in the local zone with
|
|
# MAC address 00:A0:C9:15:39:78.
|
|
#
|
|
# Alternatively, clients may be specified by interface
|
|
# by appending ":" followed by the interface name. For
|
|
# example, loc:eth1 specifies a client that
|
|
# communicates with the firewall system through eth1.
|
|
#
|
|
# SERVER Location of Server. May be a zone defined in
|
|
# /etc/shorewall/zones or $FW to indicate the firewall
|
|
# itself.
|
|
#
|
|
# The server may be further restricted to a particular
|
|
# subnet, host or interface by appending ":" and the
|
|
# subnet, host or interface. See above.
|
|
#
|
|
# The port that the server is listening on may be
|
|
# included and separated from the server's IP address by
|
|
# ":". If omitted, the firewall will not modifiy the
|
|
# destination port.
|
|
#
|
|
# Example: loc:192.168.1.3:8080 specifies a local
|
|
# server at IP address 192.168.1.3 and listening on port
|
|
# 8080. The port number MUST be specified as an integer
|
|
# and not as a name from /etc/services.
|
|
#
|
|
# PROTO Protocol - Must be "tcp", "udp", "icmp", a number,
|
|
# "all" or "related". If "related", the remainder of the
|
|
# entry must be omitted and connection requests that are
|
|
# related to existing requests will be accepted.
|
|
#
|
|
# PORT(S) Destination Ports. A comma-separated list of Port
|
|
# names (from /etc/services), port numbers or port
|
|
# ranges; if the protocol is "icmp", this column is
|
|
# interpreted as the destination icmp-type(s).
|
|
#
|
|
# This column is ignored if PROTOCOL = all but must be
|
|
# entered if any of the following ields are supplied.
|
|
# In that case, it is suggested that this field contain
|
|
# "-"
|
|
#
|
|
# CLIENT PORT(S) (Optional) Port(s) used by the client. If omitted,
|
|
# any source port is acceptable. Specified as a comma-
|
|
# separated list of port names, port numbers or port
|
|
# ranges.
|
|
#
|
|
# If you don't want to restrict client ports but need to
|
|
# specify an ADDRESS in the next column, then place "-"
|
|
# in this column.
|
|
#
|
|
# ADDRESS (0ptional) If included and different from the IP
|
|
# address given in the SERVER column, this is an address
|
|
# on some interface on the firewall and connections to
|
|
# that address will be forwarded to the IP and port
|
|
# specified in the SERVER column.
|
|
#
|
|
# If the special value "all" is used, then requests from
|
|
# the client zone given in the CLIENT(s) column with the
|
|
# destination port given in PORT(s) will be forwarded to
|
|
# the IP address given in SERVER. The value "all" is
|
|
# intended to be used when your internet IP address is
|
|
# dynamic and you want to do port forwarding or you want
|
|
# to do proxy redirection. IT SHOULD NOT BE USED IN ANY
|
|
# OTHER SITUATION.
|
|
#
|
|
# The address (or "all") may optionally be followed by
|
|
# a colon (":") an an IP address. This causes Shorewall
|
|
# to use the specified IP address as the source address
|
|
# in forwarded packets. See the Shorewall documentation
|
|
# for restrictions concerning this feature. If no source
|
|
# IP address is given, the original source address is not
|
|
# altered.
|
|
#
|
|
# Example: Forward all ssh and http connection requests from the internet
|
|
# to local system 192.168.1.3
|
|
#
|
|
# #RESULT CLIENTS SERVER(S) PROTO PORT(S) CLIENT PORT(S) ADDRESS
|
|
# ACCEPT net loc:192.168.1.3 tcp ssh,http - all

#
|
|
# Example: Redirect all locally-originating www connection requests to
|
|
# port 8080 on the firewall (Squid running on the firewall
|
|
# system)except when the destination address is 192.168.2.2
